This image depicts a sunset scene within the Dunas da Sabiaguaba Natural Park in Fortaleza, Ceará, Brazil. The foreground features extensive, undulating light-colored sand dunes. Centrally positioned is a wooden signpost, approximately 1.5 meters tall, composed of eight horizontal reddish-brown planks with blue-black Portuguese text. The text reads, from top to bottom: "NÃO MATE NADA ALÉM DE TEMPO" (Do not kill anything except time); "NÃO TIRE NADA ALÉM DE FOTOS" (Do not take anything except photos); "NÃO DEIXE NADA ALÉM DE PEGADAS" (Do not leave anything except footprints); "NÃO LEVE NADA ALÉM DE SAUDADE" (Do not take anything except longing). The sign is mounted on a white-painted wooden post. To the right of the sign, a taller, white-painted wooden structure, approximately 2 meters in height, stands partially buried in the sand. It resembles a cross or abstract form, constructed from two thick, gnarled branches, with white string wrapped around its lower section. In the mid-ground, a winding body of water, likely a river or estuary, is visible, bordered by dense green mangrove vegetation. The background reveals the ocean and faint, distant urban structures under a clear sky. The sky transitions from a warm orange-yellow hue near the horizon to a pale blue overhead, indicative of late afternoon lighting. Two indistinct human figures are seated on a distant sand dune on the far right, appearing as dark silhouettes against the sky.
